From d85a881d780cc7aaebe1b7aefcddbcb939acbe2d Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@elte.hu>

Subject: [PATCH] x86: remove various unused subarch hooks

Impact: remove dead code

Remove:

 - pre_setup_arch_hook()
 - mca_nmi_hook()

If needed they can be added back via an x86_quirk handler.
